Improvement in rail-joints



UNITED TATES PATENT EDMUN P. HYATT, OF WILTON, CONNECTICUT, ASSIGNOR OFONE-HALF HIS VRIGHT TO GEORGE QUICK AND ORVIL BROWN, OF SAME PLACE.

IMPROVEMENT INRAIL-JOINTS.

Specilication forming part of Letters Patent N0. 21 5,8 I9, dated May27, 1879; application iiled April 16, 1879.

C, and as it is of great importance to obtain as much strength aspossible at the ends of To all whom it may concern:

Be it known that I, EDMUN PERRY HYATT,

of Wilton, in the county of Fairfield and State of Connecticut, haveinvented a new and valuable Improvement in Rail-Joints; and I do herebydeclare that the following is a full,

clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a side elevation of myinvention, partly in section. Fig. 2 is a sectional end view of thesame.

This invention has relation to improved means for connectiu g togetherthe ends of railroad-rails; and the object thereof is to dispense withthe necessity of using fish-plates heretofore employed for forming therail-joint, au d therefore consists in the peculiar construction of theends of the rail in connection with a coupling-wedge, as will behereinafter described, and subsequently pointed out in the claims.

In the accompanying drawings, A B represent the two rails, formed attheir ends with swell a, to increase the strength of the rails at thatpoint and admit of their being cast with recesses b. A wedge, C, fitssnugly in the recess when the ends of the rails are brought together,and isheld therein by bolts c, passing through the rails and through thewedge C, said wedge having elongated openings d, to allow of thecontraction and expansion of the lnetal. The coupling-wedge C is formedwith inclined ends c, which t correspondingly-inclined shoulders f inthe recess I), making a very firm and rigid connection for the rails.

The recess b, it will be noticed, is inclined to correspond with theinclined sides of the wedge the rails where they join each other, and atthe same time have the recess of sufficient depth and width to receive awedge of the required strength, the ends of the rails at their sides arecast with the swell a.

The recess b having the sides thereof inclined in a direction toward thecenter of the rail, as illustrated in Fig. 2 of the drawings, morestrength is obtained at the base of the rail.

The coupling-wedge, it will be understood, is separate and independentof the rails, and can be put in place after the ends of the rails arebrought together, and be securely fastened by the bolts o and the nutsg, two bolts being used for each end of the rails.

The rails joined together as above described, and the swell upon thesides thereof, make a strong joint and save the wear and tear of therails, and insure the smooth running of the train over the joint or atthat point where the rails are connected.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The rails A B, formed with swell c and recess b, in combination withthe independent coupling-wedge C, substantially as and for the purposeset forth.

2. The rails A B, formed with swell c and inclined recess b, incombination with the couplin g-wedge C, and bolts and nuts c g,substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed. my namein the presence of two witnesses.

EDMUN PERRY HYATT.
